What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use bananas that are heavily spotted or even fully black for maximum sweetness and moistness.
- 2Toast the walnuts for 3-4 minutes in a dry pan before adding to deepen their nutty flavor.
- 3Fill only 8 muffin cups so the batter bakes into tall, domed tops instead of flat ones.
- 4Do not overmix the batter after adding flour — fold just until no dry streaks remain to keep muffins tender.
- 5Cool muffins in the pan for exactly 5 minutes, then transfer to a rack to prevent soggy bottoms.
- 6Store leftover muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 2 months.
